Mission overview
Boarding Action opens the three-mission Operation: METEORITE prequel. Official material places the operation one year before Alpha Halo and pairs Master Chief with Sergeant Avery Johnson.
Recommended loadout: Start with complementary damage types and adjust when the mission reveals its dominant engagement range.
Objective priorities
- Treat new encounter layouts as unknown rather than relying on original-campaign routes.
- Check the objective marker after large fights before searching side spaces.
- Keep complementary shield-breaking and finishing weapons.
Combat and difficulty tips
- Use the first encounter to test how the current difficulty changes enemy aggression.
- Preserve heavy ammunition until the mission establishes its priority targets.
- In co-op, assign one player to ranged control and another to close support.
